A CEO differs from a General Manager.

"A chief executive officer (CEO) is the highest-ranking executive in a company, whose primary responsibilities include making major corporate decisions, managing the overall operations and resources of a company, acting as the main point of communication between the board of directors (the board) and corporate operations and being the public face of the company. A CEO is elected by the board and its shareholders." ~ https://www.investopedia.com/terms/c/ceo.asp

"A general manager (GM) is in charge of part or all of a company's operations, including generating revenue and controlling costs." ~ https://www.investopedia.com/terms/g/general-manager.asp
